The rapid development of information technology has had a significant impact on various aspects of life, including the decision-making process that requires precision and objectivity. One of the problems often faced is product selection with various complex criteria, for example in selecting a quality drum. Drums as a percussion instrument have many variations in terms of sound quality, material, design, price, and durability, so a system is needed that can assist users in making a more rational choice. This study aims to develop a website-based Decision Support System (DSS) using the Weighted Product (WP) method to provide recommendations for drum selection. The WP method was chosen because it is able to perform calculations by considering the weight of each criterion so that the recommendation results are more objective. The system implementation is carried out through the design of a user-friendly web-based interface, making it easier for users to access, compare alternatives, and obtain recommendations without having to perform manual assessments that are time-consuming and potentially subjective. System testing was carried out by comparing the results of the system's recommendations with expert assessments, which obtained an accuracy level of 95%. These results indicate that the developed system has a high level of reliability and is suitable for use as an aid in decision-making in selecting quality drums. With this system, it is hoped that users, both beginners and professionals, will find it easier to choose drums that suit their needs and preferences.

Homecare services are increasingly recognized as a preferred healthcare option because of their practicality, flexibility, and accessibility, especially for elderly patients and individuals with physical limitations who face difficulties in reaching health facilities. This study aims to examine the relationship between consumer, provider, sociocultural, and organizational factors with patients’ preferences in selecting homecare services. Employing a quantitative approach with a descriptive analytical design, data analysis was conducted using the chi-square test to determine the significance of each factor. The findings reveal that consumer-related aspects, such as personal needs, convenience, and trust (p = 0.005), along with sociocultural influences including social norms, cultural values, and family support (p < 0.001), have a significant relationship with patients’ choices of homecare services. In contrast, provider factors (p = 0.096) and organizational factors (p = 0.161) were found to have no significant impact on the decision-making process. These results suggest that patients’ decisions are primarily shaped by internal motivations and sociocultural environments rather than institutional or organizational elements. Thus, it is essential for healthcare providers to focus on understanding community needs, cultural practices, and patient expectations to ensure that the services offered are both relevant and acceptable. By integrating cultural sensitivity and consumer-oriented strategies, homecare services can become more effective, trusted, and widely utilized within the community.

Local food such as chayote (Sechium edule) has great potential as a healthy and environmentally friendly product that can support food security and improve the economic value of local communities. The innovation of processing chayote, particularly into jam, not only helps reduce agricultural waste but also opens up promising new market opportunities. This study applied an experimental design to produce chayote jam with variations in the use of granulated sugar, glucose, and the addition of mint leaves to enhance flavor. The production stages included grating fresh chayote, cooking until the water content was reduced, adding sugar and pectin to achieve a thick and stable texture, and finally packaging the product in sterilized glass jars. An organoleptic test was conducted with 32 panelists to evaluate the color, aroma, taste, texture, and overall acceptability of the product. The results indicated that jam dominated by granulated sugar (Sample A) gained the highest level of preference, with an overall acceptance of 81%. In contrast, jam made with full glucose substitution (Sample C) received the lowest score of 66%. Generally, chayote jam had a natural green color, distinctive aroma, and thick texture that were well accepted by consumers. The main factors determining jam quality were cooking techniques, the balance of thickening agents, and the proper combination of ingredients. Therefore, chayote jam has the potential to become an innovative, healthy, and value-added local food product. Support in the form of training, technology application, and promotional strategies is essential to strengthen its competitiveness, improve farmers’ welfare, and enhance food diversification based on Indonesia’s local resources.

Fermentation of seluang fish (Rasbora spp.) pekasam is a traditional method for extending shelf life and enhancing flavor, typically produced through spontaneous fermentation dominated by lactic acid bacteria (LAB). However, uncontrolled production processes lead to significant variability in product quality. This research aims to optimize the fermentation process of seluang fish pekasam through a series of controlled microbiology-based experimental practicums. The experiments were designed to investigate the impact of two main parameters: (1) the use of a LAB starter culture isolated from high-quality pekasam, and (2) the control of incubation temperature (e.g., at 25°C and 30°C). During the fermentation period, samples were periodically analyzed to measure changes in physicochemical parameters, including pH, moisture content, and salt concentration. Microbiological analysis was performed to count the populations of LAB and other spoilage microbes. The results showed that the use of a LAB starter culture significantly accelerated the pH drop within the first 24 hours, reaching a critical pH below 4.5, which effectively inhibited the growth of pathogenic microbes. Furthermore, the optimal raw material ratio and controlled incubation temperature resulted in pekasam with a firmer texture and a more balanced sour-savory taste, differing significantly from spontaneously fermented products. Organoleptic tests confirmed panelists' preference for the product made with the optimal treatment. The conclusion of this study is that optimization through microbiology-based experimental practicums is key to the standardization and improvement of the quality and food safety of pekasam products.

Purple sweet potato yogurt is a form of local food innovation made from milk fermented by lactic acid bacteria (LAB), with the addition of purple sweet potato paste to enhance flavor and color, thereby increasing consumer appeal. During fermentation, LAB require carbon derived from carbohydrates as an energy source for their metabolism and growth. Differences in carbon sources are expected to influence and produce distinct yogurt characteristics. Therefore, this study aimed to investigate the effect of various carbon sources on the characteristics of purple sweet potato yogurt. The experiment was conducted using a Randomized Block Design (RBD) with a single treatment factor: the type of carbon source. Six treatments were tested, namely: no sugar (control), granulated sugar, palm sugar, sugarcane juice, coconut sugar, and honey. The results indicated that different carbon sources caused variations in total dissolved solids, total lactic acid bacteria, total titratable acidity, and total reducing sugars. Carbon sources significantly affected titratable acidity, reducing sugar content, total dissolved solids, color, taste, and the overall sensory evaluation of purple sweet potato yogurt. The yogurt produced exhibited titratable acidity values ranging from 1.69% to 1.86%, reducing sugar content from 1.11% to 1.46%, total LAB counts from 0.28 to 89.50 × 10¹0 CFU/g, and total dissolved solids from 10.25 to 17.75 °Brix. Sensory evaluation scores ranged as follows: color preference 2.83–4.26 (dislike to like), texture 3.43–3.76 (like), aroma 3.53–3.70 (like), taste 2.67–3.70 (dislike to like), and overall acceptability 3.43–3.90 (like).

Before entering marriage, a person will generally choose a partner who meets their criteria. Choosing a partner is not something to be done carelessly, as this decision has a significant impact on the journey of the household and the harmony of the relationship in the future. Factors influencing partner selection can be very diverse, ranging from personal values, social environment, to the influence of developments in the times and mass media. One popular cultural phenomenon that also influences is K-Pop. For some people, a deep interest in K-Pop idols or artists can form certain standards or criteria in choosing a life partner. This study aims to determine the influence of idol worship on partner selection preferences among early adult female K-Popers in West Sumatra. The study subjects were 120 people selected using a snowball sampling technique. The study used a quantitative method, with instruments in the form of an idol worship scale and a partner selection preference scale compiled by researchers based on the dimensions of idol worship by Cheung and Yue (2018) and aspects of partner selection preferences by Townsend and Roberts (1993). The results of a simple linear regression analysis indicate that, in general, idol worship has no significant effect on partner choice preferences (sig = 0.405 > 0.05). However, when examined by dimension, attachment (sig = 0.002 < 0.05) and idealization (sig = 0.001 < 0.05) significantly influence partner choice preferences. This finding indicates that emotional aspects and idealization of idols can shape the criteria or ideal image of a desired partner, although idol worship does not have a direct effect overall.
